What About Edelbrock 340 Heads?

It just gets to risky after awhile. It doesn’t make sense to push it especially in the street. I’ve run .030 quench and that was just fine enough. Normally it’s .039/.040 but not more than .050 where it is said that’s the most away you can run it before the bennifts are lost.
Thanks, that is pretty much where I am at too.
